I may be missing something, but simply dropping the @c should be
correct?  I tested info output (from makeinfo in C) and dvi output, 
and it seemed to be ok with and without the @c.  The new 
implementation will work only without the @c.

But, why was the @c added in the first place?  Is it important for
something now or was it important for some older versions of texinfo.tex
or makeinfo?

PS: there is in fact another change in behaviour that seems more 
problematic to me, the protection of the line by the @ adds a space within 
the @samp, this looks wrong and I will work on that as soon as
